Soil Changes Caused by Erosion Control Treatments on a Salt Desert Area1

Soil samples taken in the environs of gully plugs and contour furrows installed in shale-derived saline-sodic soils showed that the physical and chemical characteristics differed from the control profile. Physical measurements of moisture holding capacity, bulk density, and infiltration, varied because of fine clay deposition in the catchment basins of these structures and because of the mechanical disturbance of the shale during gully plug and furrow construction.
Electrical conductivity and sodium measurements differed from the normal profile due to leaching since construction. The movement of salts was related to the rainfall received rather than to the season. These edaphic changes would have a profound effect on the establishment, development, and growth of introduced species seeded on the treatments.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
